 During its initial development and benchmarks, we observed the following:
 
-1. The `ChannelExecutor` tremendously reduced idle CPU and max busy CPU even during peak message throughput, primarily as a result of dynamically shrinking the total `ThreadPool` to only the necessary size. This resolves one of the largest complaints large users of Akka.NET have today. However, **in order for this setting to be effective `ThreadPool.SetMin(0,0)` must also be set**. We are considering doing this inside the `ActorSystem.Create` method, those settings don't work for you you can easily override them by simply calling `ThreadPool.SetMin(yourValue, yourValue)` again after `ActorSystem.Create` has exited.

 This will enable the `ChannelExecutor` to run everywhere and all Akka.NET loads, with the exception of anything you manually allocate onto a `ForkJoinDispatcher` or `PinnedDispatcher`, will be managed by the `ThreadPool`.
 
-> [!IMPORTANT]
-> As of Akka.NET v1.4.19, we call `ThreadPool.SetMinThreads(0,0)` inside the `ActorSystem.Create` method as we've found that the default `ThreadPool` minimum values have a negative impact on performance. However, if this causes undesireable side effects for you inside your application you can always override those settings by calling `ThreadPool.SetMinThreads(yourValue, yourValue)` again after you've created your `ActorSystem`.
